Hi @mlmk0601 Whether you have ET or not, pesticides and products containing Benzene should be avoided because of their links to cancer. If your doctor brought this up specifically, maybe they feel there’s a correlation between your disease and activities or exposures that may have caused your condition? Examples: If you’re a farmer, using pesticides or herbicides your entire career this can potentially be detrimental to your health. If you worked in the auto industry using spray paints, solvents, etc.

Here is an excerpt from CDC on the effects of Benzene. I’ve put links to the full article below:

“Stay away from cigarette smoke. If you are person who smokes, try to quit. It’s also important to avoid secondhand smoke. Cigarette smoke is a major source of benzene exposure.

Pump gas carefully and use gas stations with vapor recovery systems that capture the fumes. Avoid skin contact with gasoline.

When possible, limit the time you spend near idling car engines. This can help lower your exposure to exhaust fumes, which contain benzene (as well as other potentially harmful chemicals).

Use common sense around any chemicals that might contain benzene. Limit or avoid exposure to fumes from solvents, paints, and art supplies, especially in unventilated spaces.”

With your ET, your doctor is treating you with baby aspirin to keep the platelets from forming clots. Are you taking any other medications?
